What it is
TB-500 is a synthetic peptide fragment of thymosin beta-4, a naturally-occurring protein abundant in human tissue. It has been studied in research contexts related to tissue repair signaling.
How it works
In research literature, thymosin beta-4 and its synthetic fragment are described as influencing actin sequestration, cell migration, and angiogenesis — mechanisms studied in the context of tissue repair models.
What to expect
TB-500 is generally used in cycles over several weeks for recovery and tissue-repair goals. Any response develops gradually and varies from person to person — some people may notice little or no change. Your prescriber sets the protocol, dose, and timeline. It is a research peptide, is not FDA-approved, and no specific result is promised or guaranteed. Because TB-500 appears on the WADA prohibited list, it is not suitable during sanctioned athletic competition.
Who your provider may consider it for
Your Orbit Health prescriber may consider compounded TB-500 in research-context protocols after reviewing your intake, history, and goals.
What your provider will discuss with you
- Recovery and tissue-repair goals
- Concurrent peptides or therapies
- Cancer history (a relevant consideration with peptides that influence angiogenesis)
- Injection technique and protocol
Common questions
Is TB-500 FDA-approved?
No. TB-500 is a research peptide and is not FDA-approved for any use, and compounded medications are not FDA-approved as finished drugs. It is dispensed only after a state-licensed prescriber reviews your intake.
How is it taken?
It is typically given as a small subcutaneous (under-the-skin) injection. The pharmacy supplies the exact preparation, and your provider reviews technique with you.
How long is a cycle?
It is generally used in cycles over several weeks, often with breaks. There is no single standard schedule — your prescriber sets the dose and duration based on your goals and history.
Can I take it alongside my other treatments?
Possibly, but only your prescriber can assess interactions. List everything you take — including GLP-1 medications, hormones, and supplements — during intake.
Could it affect drug testing?
TB-500 appears on the WADA prohibited list. If you are subject to anti-doping testing or sanctioned competition, it is not suitable — let your provider know.
What does the research look like?
Foundational research on thymosin β-4 is largely preclinical, and no completed, published human trials of the TB-500 fragment exist for tissue-repair indications. Human clinical evidence is limited.
Who should not use it?
It is not for anyone under 18, pregnant, or breastfeeding. Your prescriber will review your history, including any cancer history — relevant because TB-500 has been studied for effects on blood-vessel formation.
Considerations
Published research is largely preclinical. Human clinical evidence is limited. Your prescriber will discuss what is and is not known.
Regulatory note. TB-500 is a research peptide. It is not FDA-approved for any indication. Availability is subject to FDA bulk-substance status, which has been actively reviewed for research peptides; your prescriber will confirm availability at consultation.
Federal regulations (FDA compounding regulations) and state medical board rules govern what your Orbit Health prescriber can lawfully prescribe to you. See our full regulatory disclosure for active state and federal regulations affecting availability.
